Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of coal separation detection, in particular, to a coal slurry water sedimentation state detection device and method. BACKGROUND

[0002] In the field of coal washing and processing, coal slurry water sedimentation is a key link to realize solid-liquid separation, recover fine particle coal slurry and purify water quality. The sedimentation effect directly affects the subsequent coal slurry dewatering efficiency, water resource recycling and environmental protection emission indicators, so accurate detection of key parameters (such as sedimentation speed, sedimentation interface position, particle concentration distribution, etc.) in the sedimentation process is crucial to optimize process control and improve production efficiency.

[0003] The existing technology basically stays in manual observation and surface camera imaging, without studying the coal slurry water sedimentation section, and without forming the detection of parameters such as sedimentation speed, sedimentation interface position and particle concentration. For example, manual observation: judging the sedimentation state by visually observing the turbidity change in the sedimentation tank, which is highly subjective and low in efficiency, cannot obtain dynamic data in real time, and cannot quantify particle concentration and sedimentation interface migration law; or surface camera imaging: using an industrial camera to shoot images of the liquid surface area, and analyzing the surface particle distribution by combining image processing algorithms, but only shallow information of the liquid surface can be obtained, and the deep layer of the liquid cannot be penetrated, and the sedimentation section (such as particle concentration gradient at different depths and dynamic evolution of the sedimentation interface) cannot be effectively detected.

[0004] The coal slurry water sedimentation process has significant nonlinear characteristics, with a wide range of particle sizes (microns to millimeters), large concentration gradient, and dynamic changes of the sedimentation interface over time, so real-time monitoring of parameters at multiple positions and depths of the section is required. The existing technology lacks section penetration ability due to single detection means, which leads to inaccurate evaluation of the sedimentation effect and difficulty in meeting the needs of intelligent and refined process control.

DETAILED DESCRIPTION

[0021] The present application will be further described in detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0022] In order to make the drawing simple, only the parts related to the present application are shown in each figure, which do not represent the actual structure of the product.

In this paper, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0026] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0027] As Figures 1-5 shown, which shows a coal slime water sedimentation state detection device in an embodiment of the present application, comprising: a box body 1, a container 2 for containing coal slime water is arranged in the box body 1; An X-ray emitting assembly 3 is arranged in the box body 1 and located at one side of the container 2, the X-ray emitting assembly 3 is used for emitting X-ray to the coal slime water in the container; An X-ray receiving assembly 4 is arranged in the box body 1 and located at the other side of the container 2, the X-ray receiving assembly 4 is arranged opposite to the X-ray emitting assembly 3, the X-ray receiving assembly 4 is used for receiving the X-ray after penetrating the coal slime water and generating corresponding image data; A controller is electrically connected with the X-ray emitting assembly 3 and the X-ray receiving assembly 4 respectively, the controller is used for controlling the X-ray emitting assembly 3 to emit X-ray to the container 2, and the controller is used for controlling the X-ray receiving assembly 4 to receive image data.

[0028] For example, as Figure 1As shown, the box body 1 is in the shape of a closed cuboid, and a darkroom is formed inside the box body 1. The space inside the box body 1 forms a darkroom, which provides the best detection environment for X-rays. The container 2 is placed in the box body 1, and the container 2 is used to hold the slime water. The container 2 is made of a transparent material with low X-ray attenuation, such as organic glass, which can minimize the impact of X-ray penetration and ensure image quality. The shape of the container 2 is generally a regular cylinder or a cuboid to facilitate uniform X-ray penetration and subsequent image analysis.

[0029] The X-ray emitting assembly 3 is located on one side of the container 2, and the main component of the X-ray emitting assembly 3 is an X-ray generator 301. The X-ray generator 301 can generate an X-ray beam to penetrate the slime water. It should be noted that the X-ray generator 301 is wrapped in a lead seal outside, but the lead seal does not block the X-ray emission of the X-ray generator 301. The X-ray receiving assembly 4 is installed on the other side of the container 2, corresponding to the X-ray emitting assembly 3. The X-ray receiving assembly 4 is used to receive the detector of the X-ray after penetrating the slime water. The detector can convert the received X-ray signal into an electrical signal or a digital signal, and further generate image data for analysis.

[0030] The controller is electrically connected to the X-ray emitting assembly 3 and the X-ray receiving assembly 4 through wires. The controller usually uses a high-performance microprocessor or an industrial control computer, which has powerful data processing and control capabilities. It can control the operation of the X-ray emitting assembly 3, such as the time and intensity of X-ray emission; at the same time, it can also control the X-ray receiving assembly 4 to accurately receive image data and perform preliminary processing and analysis on these data.

[0031] Before the preparation work, first connect the device to the power supply and start the controller. The controller first performs initialization detection on each component to ensure that the X-ray emitting assembly 3, the X-ray receiving assembly 4, etc. can work normally. At the same time, check whether the container 2 is clean and free of impurities, and if necessary, perform cleaning and drying treatment.

[0032] During the detection work, the coal slime water to be detected is injected into the container 2 through the sampling pipe 6 to reach the appropriate liquid level. Then, the controller issues an instruction to trigger the X-ray emitting assembly 3 to work. The X-ray generator 301 generates an X-ray beam to penetrate the slime water in the container 2. During the penetration process, the X-ray will be attenuated due to different particle concentrations and distribution in the slime water. The detector in the X-ray receiving assembly 4 receives these attenuated X-rays and converts them into image data.

[0033] The X-ray receiving assembly 4 transmits the generated image data to the controller. The controller processes and analyzes the image using pre-programmed image analysis algorithms. Through the algorithms, key parameters such as settling velocity, settling interface position, and particle concentration distribution during the settling process of slime water can be calculated, and these analysis results can be displayed on the display screen of the controller in an intuitive manner or transmitted to an external computer for further processing and storage.

[0034] In the above scheme, the detection device of the present application breaks through the limitations of manual observation and surface camera imaging in the prior art, and can deeply detect the situation of the slime water settling section. Through X-ray imaging and analysis, multiple key parameters such as settling velocity, settling interface position, and particle concentration can be obtained simultaneously, providing rich data support for a comprehensive understanding of the slime water settling process. The subjectivity brought by manual observation is avoided. Manual observation is easily affected by factors such as the personal experience of the observer and visual errors, while the device can more objectively and accurately reflect the real state of slime water settling through accurate physical detection and data analysis. The slime water settling process can be monitored in real time, and dynamic changes in the settling process can be captured in a timely manner. Compared with the traditional detection method which can only obtain static or intermittent data, the device can provide timely information for real-time adjustment and optimization in the production process.

[0035] In some examples, the box 1 is a closed structure, and the inner wall of the box 1 is provided with a lead shielding layer. The lead shielding layer has good radiation shielding performance and can effectively block the leakage of X-rays. The lead shielding layer ensures that the radiation dose outside the box 1 is within a safe range during normal operation of the device. Specifically, the lead shielding layer is made of high-purity lead and uniformly covers the inner wall of the box 1. During installation, ensure that the lead shielding layers are tightly jointed without gaps. For possible gaps or interfaces, special sealing materials are used to prevent X-rays from leaking from these parts.

[0036] For example, as shown in Figure 4 When the X-ray emitting assembly 3 starts emitting X-rays, the lead shielding layer immediately comes into play. The lead shielding layer can absorb and block most of the scattered and leaked X-rays, so that the X-rays are as localized as possible within the box 1 for detection, reducing the radiation hazards to the external environment and personnel. To further ensure safety, the device is provided with a safety interlock mechanism. The controller will monitor the state of the lead shielding layer and the radiation dose around the box 1 in real time. Once an abnormal increase in radiation dose is detected, or the risk of radiation leakage due to damage to the lead shielding layer, the controller will immediately take measures to automatically cut off the power supply of the X-ray emitting assembly 3, and at the same time send out an alarm signal to remind the operator to pay attention to safety. The closed box 1 structure and the lead shielding layer not only block radiation, but also reduce the interference of external environmental factors on the detection process, such as external light, other radiation sources, etc., thereby improving the stability and reliability of the detection results.

[0037] In some examples, the X-ray emitting assembly 3 includes: an X-ray generator 301, housed within the enclosure 1 and located on one side of the container 2. This high-performance X-ray generator 301 possesses stable emission performance and a wide energy adjustment range. Its internal structure is complex, containing core components for generating X-rays, such as a cathode and anode. By precisely controlling the acceleration and impact process of the electron beam, it generates an X-ray beam that meets the detection requirements. An electric beamset 302, also housed within the enclosure 1 and located between the X-ray generator 301 and the container 2, is used to adjust the direction of the X-rays emitted by the X-ray generator 301, ensuring that the X-rays penetrate the container 2 perpendicular to its axis. The electric beamset 302, installed between the X-ray generator 301 and the container 2, consists of an adjustable aperture driven by a motor. The opening degree and angle of the aperture can be precisely controlled by a controller, thereby adjusting the direction of the X-rays emitted by the X-ray generator 301 to ensure that the X-rays penetrate the container 2 perpendicular to its axis. This ensures that the X-rays follow a consistent path when penetrating the coal slurry, reducing imaging errors caused by deviations in the ray angle.

[0038] For example, such as Figure 1 As shown, before each inspection begins, the controller directs the motorized beam 302 to perform a radiation calibration operation. By adjusting the position and angle of the aperture, the central axis of the X-ray beam is precisely aligned with the center of the cross-section of container 2, ensuring that the radiation is perpendicular to the axis of container 2. This calibration process can be assisted by specialized calibration instruments to ensure accuracy.

[0039] During the detection process, if the concentration of the coal slurry changes, or according to different detection requirements, the controller will automatically adjust the motorized beam emitter 302 and the X-ray generator 301 dynamically. For example, when the coal slurry concentration is high, the X-ray energy is appropriately increased, and the motorized beam emitter 302 is adjusted to make the beam more concentrated, ensuring that it can penetrate the coal slurry and obtain a clear image. Ensuring that the X-rays penetrate the coal slurry vertically and uniformly avoids image distortion and other problems caused by oblique penetration, greatly improving the clarity and accuracy of the image and facilitating more precise analysis of the coal slurry settling effect. This device can flexibly adjust the X-ray parameters and direction according to the different properties of the coal slurry and detection requirements, making it applicable to the detection of coal slurry with various concentrations and particle distributions, thus expanding the device's application range.

[0040] In some examples, the 1-ray receiving assembly 4 includes a DR flat panel detector 401 arranged in the box 1 and located on the other side of the container 2, the DR flat panel detector 401 is arranged opposite to the motorized beam light 302 with respect to the container 2, and the DR flat panel detector 401 is used to capture image information after the X-rays penetrate the coal slurry and transmit the image information to the computer. The DR flat panel detector 401 as the key equipment of the X-ray receiving assembly 4 adopts advanced digital flat panel detector technology. The DR flat panel detector 401 is internally composed of a large number of detector units, which can quickly and accurately respond to X-rays and convert them into electrical signals. The effective detection area of the detector matches the size of the container 2, ensuring that the X-ray signal after penetrating the coal slurry can be completely received. At the same time, the detector has high resolution and sensitivity, which can capture weak X-ray signal changes. The arrangement mode of the DR flat panel detector 401 and the motorized beam light 302 ensures that the X-rays can accurately enter the detector after penetrating the coal slurry along a straight line, reducing scattering and interference in the process of ray propagation and improving the quality of imaging.

[0041] For example, as shown in Figure 1 When the X-rays penetrate the coal slurry, the DR flat panel detector 401 starts to work. The detector units receive X-ray photons and convert them into electrical signals, which are processed through a series of circuits and analog-to-digital converted to finally generate digital image data. These image data are stored in the buffer inside the detector in a certain format, waiting for transmission. The detector transmits the collected image data to the computer or controller in real time through a high-speed data transmission interface such as USB3.0 or Ethernet interface. In the transmission process, data checksum and error correction techniques are used to ensure the integrity and accuracy of the data.

[0042] The DR flat panel detector 401 can capture the subtle structure and particle distribution changes inside the coal slurry, providing high-resolution images that help to analyze the particle concentration changes, the position and shape of the sedimentation interface, and other information during the coal slurry sedimentation process in more detail. The rapid real-time transmission of image data enables the operator to obtain the detection results in time for subsequent analysis and processing, meeting the real-time monitoring needs of the coal slurry sedimentation effect.

[0043] In some examples, the container 2 includes a cylinder 20, the top of which is detachably provided with an end cover 21, and the bottom of which is detachably provided with a sealing cover 22; one end of the sampling pipe 6 penetrates the end cover 21 and communicates with the inside of the cylinder 20, and the other end is communicated with the material pool 7 containing the coal slurry to be detected; one end of the cleaning pipe 8 penetrates the end cover 21 and communicates with the inside of the cylinder 20, and the other end is communicated with the clean water pool 10, and the cleaning pipe 8 is used to inject clean water into the cylinder 20 to clean the inner wall of the cylinder 20 after detection.

[0044] For example, as shown in Figure 3As shown, the top and bottom of the barrel 20 are designed as detachable structures, the top is sealed by the end cover 21, and the bottom is sealed by the sealing cover 22. The end cover 21 and the sealing cover 22 are sealed with sealing pads between them and the barrel 20 to ensure that the slime water does not leak during the detection process. The end cover 21 can be directly buckled on the top of the barrel 20 to seal the top of the barrel 20, but to achieve the automation degree of the barrel 20 drainage, the sealing cover 22 needs to be automatically opened and closed, only need to install a straight stroke telescopic mechanism 12 on the inside bottom of the box 1, specifically, one end of the sealing cover 22 is hinged to the bottom of the barrel 20, and the piston end of the straight stroke telescopic mechanism 12 is abutted or hinged with the end cover 21, so that when the piston end reciprocates, it can drive the sealing cover 22 to open or close, and the straight stroke telescopic mechanism 12 is electrically connected with the controller, which controls the straight stroke telescopic mechanism 12 by the controller.

[0045] The sampling pipe 6 penetrates the end cover 21 and communicates with the inside of the barrel 20 at one end, and is connected to the material pool 7 containing the slime water to be detected at the other end. The sampling pipe 6 is made of acid and alkali resistant and wear resistant hose, and its pipe diameter is moderate, which can not only ensure the smooth extraction of the slime water, but also prevent large particle impurities from blocking the pipeline. The end cover 21 is provided with a gas outlet hole 23.

[0046] The cleaning pipe 8 penetrates the end cover 21 and communicates with the inside of the barrel 20 at one end, and is connected to the clean water pool 10 at the other end. The cleaning pipe 8 is also made of acid and alkali resistant and wear resistant pipe material, and its pipe diameter is generally slightly larger than that of the sampling pipe 6, so as to ensure sufficient cleaning water volume. A spray head or flushing device is installed at the end of the cleaning pipe 8 inside the barrel 20, for uniformly spraying clean water into the barrel 20 to clean the inner wall of the barrel 20 after detection.

[0047] Before detection, the controller starts the water pump 11 connected with the sampling pipe 6. The water pump 11 extracts the slime water in the material pool 7 into the barrel 20 through the sampling pipe 6, and when the liquid level in the barrel 20 reaches the preset height, the liquid level meter 13 sends a signal to stop the water pump 11 to complete the sampling process.

[0048] After the detection is completed, the sealing cover 22 at the bottom of the barrel 20 is opened to drain the slime water in the barrel 20. Then the water pump 11 connected with the cleaning pipe 8 is started, and the clean water in the clean water pool 10 enters the barrel 20 through the cleaning pipe 8. The spray head or flushing device at the end of the cleaning pipe 8 sprays clean water at a certain angle and pressure onto the inner wall of the barrel 20 to clean the barrel 20. The sewage after cleaning is discharged through the drain at the bottom of the barrel 20.

[0049] The detachable design of the cylinder 20 allows for convenient cleaning, inspection, and maintenance before and after testing. The sampling tube 6 and cleaning tube 8 enable automatic extraction of coal slurry water and automatic cleaning of the cylinder 20, greatly improving work efficiency and reducing the tediousness of manual operation.

[0050] In some examples, water pumps 11 are installed on the sampling pipe 6 and the cleaning pipe 8, respectively. These two water pumps 11 are typically of corrosion-resistant, flow-adjustable type, such as electromagnetic diaphragm pumps or centrifugal pumps. The motors of the water pumps 11 are electrically connected to the controller via wires. The controller can control the start, stop, and operating speed of the water pumps 11 as needed, thereby precisely controlling the amount of coal slurry water extracted and the flow rate of the cleaning water. A vortex elbow 9 is installed at one end of the cleaning pipe 8 inside the cylinder 20. The outlet of the vortex elbow 9 faces the nearest inner wall of the cylinder 20, allowing the clean water to enter the cylinder 20 in a high-speed tangential rotation. This creates a strong vortex inside the cylinder 20, enhancing the cleaning effect on the inner wall of the cylinder 20.

[0051] For example, such as Figure 2 and Figure 3 As shown, during the sampling process, the controller controls the water pump 11 on the sampling tube 6 to operate based on the signal fed back by the level gauge 13. When the level gauge 13 detects that the liquid level inside the cylinder 20 is close to the preset high level, the controller gradually reduces the speed of the water pump 11, thus slowing down the extraction speed of the coal slurry water. When the liquid level reaches the preset high level, the controller stops the water pump 11, achieving precise liquid level control and preventing the coal slurry water from overflowing. During cleaning, the controller starts the water pump 11 on the cleaning pipe 8, and clean water enters the cylinder 20 through the vortex bend 9 under pressure. The vortex bend 9 causes the clean water to enter the cylinder 20 at high speed in a tangential direction, forming a vortex inside the cylinder 20. The vortex can evenly wash the inner wall of the cylinder 20, washing off the coal slurry particles attached to the inner wall of the cylinder 20, and discharging them from the cylinder 20 along with the cleaning water.

[0052] By coordinating the controller and the level gauge 13, precise control of the liquid level during sampling is achieved, avoiding the problems of excessively high or low liquid levels that may occur with manual control. This ensures consistent sampling volume of coal slurry water for each test, improving the repeatability and comparability of the test results. The vortex elbow 9 creates a swirling cleaning method with stronger cleaning capabilities than ordinary flushing methods. It can more thoroughly clean the inner wall of the cylinder 20, reducing the residue of coal slurry particles on the inner wall of the cylinder 20, minimizing interference with subsequent test results, and also saving cleaning water and time.

[0053] In some examples, a temperature and humidity control device is provided in the box 1, which is composed of a temperature control module and a humidity control module. The temperature control module can use a combination of heating wires and cooling fins to adjust the temperature in the box 1. The humidity control module adjusts the humidity in the box 1 through a humidifier and a dehumidifier. These modules are electrically connected to the controller and are controlled by the controller. Temperature and humidity sensors are provided to monitor the temperature and humidity in the box 1 in real time. The sensors feed the real-time temperature and humidity data to the controller, which adjusts the temperature and humidity control device according to the preset temperature and humidity values.

[0054] For example, as shown in Figure 1 Before the detection starts, the operator sets the target temperature and humidity values in the box 1 on the controller according to the requirements of the slime water settlement detection. The controller controls the operation of the temperature and humidity control device according to the real-time temperature and humidity data fed back by the sensors. If the temperature in the box 1 is lower than the target temperature, the controller starts the heating wires to heat up; if the temperature is higher than the target temperature, the controller starts the cooling fins to cool down. The humidity control is similar, when the humidity is lower than the target value, the humidifier is started to increase the humidity; when the humidity is higher than the target value, the dehumidifier is started to reduce the humidity. During the detection process, the sensors continuously monitor the changes of the temperature and humidity in the box 1. Once the temperature or humidity deviates from the preset range, the controller will respond immediately and adjust the working state of the temperature and humidity control device in time, so that the temperature and humidity in the box 1 can always be kept within a stable range.

[0055] Through accurate control of the temperature and humidity in the box 1, a stable environmental condition is provided for the slime water settlement detection. Changes in temperature and humidity can affect the physical properties and settlement process of slime water, and a stable environment can reduce the interference of these factors on the detection results and improve the accuracy and reliability of the detection results. Suitable temperature and humidity environment can help to prolong the service life of various components in the device. For example, high humidity can cause electronic components to be damaged by moisture, and high or low temperature can also affect the performance and life of X-ray generator 301, detector and other equipment. Through the temperature and humidity control device, these equipment components can be effectively protected, and the equipment maintenance cost can be reduced.

[0056] In some examples, a waterproof aerogel layer 201 is provided on the inner wall of the cylinder 20.

[0057] For example, as shown in Figure 3As shown, the aerogel has extremely low density and porosity, while also exhibiting excellent waterproof and anti-adhesion properties. This aerogel layer is relatively thin, yet it effectively reduces the adhesion of coal slime particles to the inner wall of the cylinder 20. During the coal slime water entering the cylinder 20 for testing, the waterproof aerogel layer 201 plays a crucial role. Due to the special structure and surface properties of the aerogel, the adhesion between the coal slime particles and the inner wall of the cylinder 20 is significantly reduced. When the testing is completed and the coal slime water is discharged from the cylinder 20, most of the coal slime particles are discharged with the water flow, reducing the residue of coal slime particles on the inner wall of the cylinder 20. The waterproof aerogel layer 201 makes the cleaning process easier when cleaning the cylinder 20. Clean water can more easily wash away the small amount of coal slime particles remaining on the inner wall of the cylinder 20, improving cleaning efficiency and reducing the time and water consumption required for cleaning. It also reduces the adhesion of coal slime particles to the inner wall of the cylinder 20, avoiding cross-contamination between different batches of tests. If coal sludge particles remain on the inner wall of the cylinder 20, it may affect the results of subsequent tests. The waterproof aerogel layer 201 effectively solves this problem, ensuring the accuracy of each test result. It reduces the difficulty and workload of cleaning the cylinder 20, lowering maintenance costs. Frequent use of chemical cleaners or high-intensity cleaning operations are unnecessary, saving on cleaning material costs and reducing the risk of damage to the cylinder 20 due to improper cleaning.

[0058] In some examples, a level gauge 13 is also provided on the end cap 21. The level gauge 13 is a level electrode and is electrically connected to the controller. The level gauge 13 has a high level detection point 1301 and a low level detection point 1302. The level gauge 13 is used to detect the liquid level height in the cylinder 20.

[0059] For example, such as Figure 3 As shown, the level gauge 13 is an ultrasonic level gauge installed on the end cap 21. The level gauge 13 can accurately convert the received weak reflected signal into level data. The high-level detection point 1301 is set at approximately 90% of the height of the cylinder 20. This height ensures that the cylinder 20 contains enough coal slurry for detection while preventing the coal slurry from overflowing during the detection process. The low-level detection point 1302 is set near the bottom of the cylinder 20, typically 70% from the bottom, and is used to hold different volumes of coal slurry.

[0060] A method for detecting the settling state of coal slurry water includes the following steps: S1, the bottom cover 22 of the cylinder body 20 is closed, and the sampling pipe 6 transports the coal slime water to be detected into the cylinder body 20; when the detection starts, the controller issues an instruction to drive the bottom cover 22 of the cylinder body 20 to close, so as to ensure that the cylinder body 20 is well sealed. Subsequently, the controller starts the water pump 11 on the sampling pipe 6, and the water pump 11 transports the coal slime water in the material pool 7 containing the coal slime water to be detected into the cylinder body 20 through the sampling pipe 6. In the transportation process, the filter screen on the sampling pipe 6 filters out large-particle impurities in the coal slime water, so as to ensure that the coal slime water entering the cylinder body 20 is representative.

[0061] S2, the liquid level meter 13 detects the liquid level height in the cylinder body 20, and transmits the liquid level height signal detected by the liquid level meter 13 to the controller, so as to control the water pump 11 of the liquid taking pipe to stop; the liquid level meter 13 monitors the liquid level height in the cylinder body 20 in real time, and continuously transmits the liquid level data to the controller. When the liquid level gradually rises to the high detection point 1301 of the liquid level meter 13, the liquid level meter 13 sends a signal. After the controller receives the signal, the water pump 11 of the sampling pipe 6 is immediately controlled to stop working, so as to accurately control the liquid inflow amount of the cylinder body 20, and prevent the coal slime water from overflowing.

[0062] S3, the temperature and humidity control device regulates the temperature and humidity in the box body 1; the controller starts the temperature and humidity control device, which regulates the temperature in the box body 1 according to the preset temperature parameter. The temperature sensor monitors the temperature in the box body 1 in real time, and feeds back the data to the controller. If the temperature is lower than the preset value, the heating module starts to increase the temperature; if the temperature is higher than the preset value, the refrigeration module starts to decrease the temperature, so that the temperature in the box body 1 is stabilized in a range suitable for coal slime water sedimentation detection; the control of humidity is also similar, when the humidity is lower than the target value, the humidifier is started to increase the humidity; when the humidity is higher than the target value, the dehumidifier is started to decrease the humidity, so as to reduce the influence of the environmental temperature and humidity on the detection result.

[0063] S4, the X-ray generator 301 emits X-rays to the electric beam light device 302, the electric beam light device 302 adjusts the angle of the X-rays to the cylinder body 20, and then the X-rays penetrate the cylinder body 20 and the coal slime water in the cylinder body 20; the controller triggers the X-ray generator 301 to work, and the X-ray generator 301 generates X-rays and emits them to the electric beam light device 302. The electric beam light device 302 accurately adjusts the direction of the X-rays according to the pre-set parameters, so as to ensure that the X-rays penetrate the cylinder body 20 and the coal slime water in the cylinder body 20 perpendicularly to the axis of the cylinder body 20. In the penetration process, the X-rays are attenuated due to the particle concentration and distribution difference of the coal slime water.

[0064] S5, the DR flat panel detector 401 captures image information after the X-ray penetrates the coal slime water, and transmits the image information to the computer, and the computer receives the image data and analyzes the coal slime water settling effect through a preset algorithm; the X-ray after penetrating the coal slime water reaches the DR flat panel detector 401, the detector converts the X-ray signal into an electrical signal, and further generates digital image data. These image data are quickly transmitted to the computer through the data line. The preset algorithm in the computer processes and analyzes the image, identifies the settling interface of the coal slime water, calculates the settling speed, particle concentration distribution and other parameters, so as to evaluate the settling effect of the coal slime water.

[0065] S6, after the detection is completed, the bottom cover 22 of the cylinder 20 is opened, the coal slime water is discharged from the cylinder 20, and the water pump 11 of the cleaning pipe 8 is started to clean the cylinder 20. After the detection is completed, the controller controls the bottom cover 22 of the cylinder 20 to be opened, and the coal slime water in the cylinder 20 is discharged under the action of gravity. Subsequently, the controller starts the water pump 11 on the cleaning pipe 8, and the clean water from the clean water tank 10 enters the cylinder 20 through the cleaning pipe 8. The vortex elbow 9 at the end of the cleaning pipe 8 makes the clean water enter the cylinder 20 at a tangent, forming a spiral flow, and efficiently cleaning the inner wall of the cylinder 20, so that the residual coal slime particles are washed clean, and the next detection is prepared.

[0066] In summary, the whole process of automatic detection: the whole detection process from sampling, liquid level control, environment control, detection to cleaning, realizes automatic operation, greatly improves the detection efficiency, reduces the error and uncertainty caused by manual intervention. Compared with the traditional manual detection method, the detection cycle is greatly shortened, which can meet the real-time and rapid detection demand of the coal slime water settling effect of the coal preparation plant. Through the X-ray imaging technology and the advanced image analysis algorithm, multiple key parameters in the coal slime water settling process can be accurately obtained, and the settling effect of the coal slime water can be comprehensively and accurately evaluated. It provides reliable data support for the coal preparation plant to optimize the coal slime water treatment process and adjust the amount of reagent added, which helps to improve the efficiency and quality of coal slime water treatment and reduce production cost. The automatic cleaning process effectively removes the coal slime residues on the inner wall of the cylinder 20, reduces the workload and difficulty of equipment maintenance. At the same time, the design of each part and the optimization of the working process make the equipment run more stably and reliably, reduce the occurrence rate of equipment failure, and prolong the service life of the equipment.
